What's the difference between mind reading and micro-expression! Which is easier to learn and which is more accurate?

Micro-expression is a branch of mind reading, including mind reading, which consists of micro-expression, body language, deep semantics, sound information and so on. Accuracy 100%. After all, this is a science, not a myth. If you do something wrong, you can only say that you don't have enough time to practice well. For example, pupil dilation is definitely a positive reaction, but the observer did not see it, so it is not a question of accuracy. In addition, psychology involves precision.
